I am trying to connect my computer to a Bluetooth module named "HC-08" which is similar to HM10. Since my computer has not Bluetooth version 4.0 I had to use a USB dongle (CSR) which has Bluetooth version 4.0 on it. With this dongle my computer can see name of module but failed in pairing. I also did it with Microsoft Surface Pro 3 which has a Bluetooth version 4.0 on it and it did not work, neither. For better understanding of my situation I should say that I configured HC-08 to "Slave" mode by AT Commands. Is there anything that you can suggest to me? Specially for HC-08's configurations.
